A tsunami is a huge wave in the ocean that develops as a result of an earthquake. It can reach a height of 100 feet (30 meters). A tsunami can travel even faster than a commercial jet. This powerful wallof water reaches the coast and cause a lot of damage.
Usually, it is an underwater earthquake that causes a tsunami to develop. This happens when the plates underneath the Earth's surface move so that one slips under another. From deep in the ocean the energy of the earthquake causes the water level to rise above sea level. Gravity causes the water to spread into a wave that travels at an incredible speed and with amazing power. A tsunami gets bigger as it gets closet to shore. When it hits shallow water the huge wave travels more slowly. The water from along the shore moves into the ocean, and then the massive wave crashes into the shore and keeps traveling inland.
A tsunami is a series of great sea waves caused by an underwater earthquake, landslide, or volcanic eruption. More rarely, a tsunami can be generated by a giant meteor impact with the ocean.
Tsunami (pronounced soo-NAH-mee) is a Japanese word. Tsunamis are fairly common in Japan, and many thousands of Japanese have been killed by them in recent centuries
A tsunami is not a single wave but a series of waves, also known as a wave train. The first wave in a tsunami is not necessarily the most destructive. Tsunamis are not tidal waves.
Tsunami waves can be very long (as much as 60 miles, or 100 kilometers) and be as far as one hour apart. They are able to cross entire oceans without great loss of energy. The Indian Ocean tsunami traveled as much as 3,000miles (nearly 5,000 kilometers) to Africa, arriving with sufficient force to kill people and destroy property.

Tsunamis are not always colossal waves when they come into the shore. In fact most tsunamis come in a series of smaller waves Nevertheless, there is destruction of life and of property by floating debris and impact of water. The tsunami produces a series of rushing waves and also a series of withdrawals.However, we need to take into consideration the effect of the tsunami reaching the shore. The speed is diminished but the wave height is increased drastically.
How Do Tsunamis Form?
Tsunamis Can form in many different ways such as; underwater earthquakes, undersea landslides, underwater volcanic eruption, or by asteroid impact.
Underwater earthquakes occur between the tectonic plates and cause displaced water to move forcefully causing a tsunami wave as the water tries to restabilize. Underwater landsides can be caused by bigger earthquakes and as such crate a tsunami wave in the making as the water recuperates. Undersea volcanic eruptions can cause enough force to displace and uplift the ocean so that a tsunami wave is formed. Lastly an high impact from an asteroid would disturb the ocean below it and the momentum from the asteroid would betransferred to the water crating a wave.
